NEW SYNTHESIS OF DIALKOXYTHIOXAPHOS-PHORANESULFENYL BROMIDES AND CHLORIDES

Abstract The synthesis of new pseudohalogen thioxaphosphoranesulfenyl bromides by simple bromination of bis(dialkoxythiophosphoryl)disulfides is presented. The new bromides turned out to be excellent thiophosphorylating agents, as well as substrates for a novel, highly efficient preparation of dialkoxythioxaphosphoranesulfenyl chlorides 4.
